I say "portable" but I only mean self powered. It seems all the units on the market have super long (20+ hour) battery lives. I want more power and less life. Enough for one beach trip and a recharge.
I was thinking of building a box I could power with a deep cycle car/boat battery. Just looking some guidance.
Better to use car speakers and a car amplifier, or internally amplified speakers and an inverter? Any help or advice would be appreciated.
my other idea is to buy a home system like (http://www.samsclub....prod18230353.ip) and build it into a custom box with a battery and a 120 inverter.
